- irertain new and useful Improvements in Filling-De:

teeter Mechanism for Looms, of which the following is a specification.

My inventionrelates to filling detector mechanism for weft replenishing looms, and the object of my in- .vention is to provide a very sensitive and delicate fill- .ing detector mechanism having a filling feeler or detector located preferably on the end of theiloom oppo site'fmm the magazine, on'which end is a single shuttle boi, said filling detector or feeler being adapted'to ieel through an opening in the wall of the-shuttle box or.

the binder,'- and into the shuttle; toengage with the fillihg on thebobbin, a't'every forward movement of the andlon the substantial: exhitustion' oi filling; or

.- exhanstioit' to predeterminedpoint, to operate, mech 2p anisni to the weft replenishing, mechanism to 'supplyiresh filling, in the usual and well known'way.

. .$!y improvements may be. adapted to beapplied to,

. andg used in vconnection with any well known weftrepairman-100 16; the Northrop type, hum-8.8 is shown aliddesp i e in U. -s. letters Patent, Nof,529',943, and

in which,,on the substantial enhaustion 0i filling in the ic'tivo shuttle, a (lager is brought into-position to be .ngagedby abunter on the lay, to eause the operation of. thetransferrer, and 'the supply. oiiresh filling fronm the magazine, in the usuaLand well knowl liw'ay.

I have only shown in th e drawing, a detached portion of the end ofa loom on which is the stationary shuttle box, opposite from: themagazine end of the loom,

with my improvements appliedthereto, sufficient to- 3 5-'enabl those skilled in the art to understand the'construe'tion and operation thereof;

Referring to the drawingz Figure 1 is a. .plan view of the breast-beam, the lay, and the shuttle box, on the right handend of the loom, with my improvements 4 0 applied thereh), and'shown partially in section. Fig.

Extending inwardly from the slotted shipper lever plate 3 is a stand 12, which-has at its inner end an up ward projection 12 forming a guide for a longitudinally moving filling detector or feeler 13, which consists in this instance of a piece of wire preferably bent into the shape shown at its iiiner.",end 13, which end, on the forward beat of the lay, is adapted to enter an opening 6. through the shuttl bi'ngler 6, and an opening 14 in the shuttle 14, to engage'the filling 15f on he bobbin 15. The opposite end of the filling detector or feeler 13 is pivotally connected'to one arm of an arigle or hell crank'levr l6, pivotally mounted on a stud 17 fast on the stand 12. r 7

' A light spirally coiled :watch or leaf spring" 18 is in this instaneeattached'to the angle lever 16, and acts to move inward-1y the feeI e r.13. The opposite end of the angle lever 16 has pivotallyattached thereto the outer end of a wire rod 19. The iliner of the wire rod 19 issupported'and movable longitudinally in a side exhas a hub'21" fast on a roek shaft 22, mounted in suitable bearings at the rear of the breast-beam. The op poflite end of the rock shaft 22 carries a dagger, not shown, which is adapted to be moved into the path of a hunter carried on the lay, by the rocking of the. shaft 22,.in the usual and well known way. I

When the dagger on the rock-shaft 22 is moved into "the'path of the bunterbn-the lay, the transferrer mech anism' is operated in the usual and well,.knownway,.,

The pin 30, extends into and has alongitudinal niovement in an opening in the outer: end of tha arm 20, see Fig. 1. The operation of'my' improvements will be readily understood by those skilledin the In the normal operation of theldbin -tlie engagement suitably pivoted on-a'stationaiy part-of the loom.
